 * **No pushing directly to the master branch**.
 * **All modifications** must be made in a **pull-request** to solicit feedback from other contributors.
 * Pull-requests cannot be merged before CI runs green and two reviewers have given their approval.
-* All code changed should be formated by running `cargo fmt -- --config=merge_imports=true`
+* Contributors should adhere to the [Parity Ethereum Style Guide](https://wiki.parity.io/Parity-Ethereum-Style-Guide).
 
 ### Recommendations
 
-* **Non-master branch names** *should* be prefixed with a short name moniker, followed by the associated Github Issue ID (if any), and a brief description of the task using the format `<GITHUB_USERNAME>-<ISSUE_ID>-<BRIEF_DESCRIPTION>` (e.g. `gavin-123-readme`). The name moniker helps people to inquiry about their unfinished work, and the GitHub Issue ID helps your future self and other developers (particularly those who are onboarding) find out about and understand the original scope of the task, and where it fits into Parity Ethereum [Projects](https://github.com/openethereum/openethereum/projects).

-## OpenEthereum v3.3.2
+OpenEthereum v3.0.0 is the first release of OpenEthereum client as part of OpenEthereum project, divested from Parity Technologies.
 
-Enhancements:
-* London hardfork block: Sokol (24114400)
+This release marks the transition from Parity Technologies infrastructure and bootnodes to the one managed by OpenEthereum project.
 
-Bug fixes:
-* Fix for maxPriorityFeePerGas overflow
+Parity-Ethereum v2.7 users can continue using their existing data folders. Command-line interface has also stayed identical.
+Unless specified otherwise, OpenEthereum v3.0.0 will detect if the user's database in the old Parity-Ethereum default path,
+and only if it's not found will write to the new default location.
 
-## OpenEthereum v3.3.1
+This release includes several major improvements to network and database stack:
+- Support for `eth/64` protocol and Node Discovery v4 `Ethereum Node Records` extension.

+OpenEthereum keys generator.
+  Copyright 2015-2020 Parity Technologies (UK) Ltd.
+
+Usage:
+    ethkey info <secret-or-phrase> [options]
+    ethkey generate random [options]
+    ethkey generate prefix <prefix> [options]
+    ethkey sign <secret> <message>
+    ethkey verify public <public> <signature> <message>
+    ethkey verify address <address> <signature> <message>
+    ethkey recover <address> <known-phrase>
+    ethkey [-h | --help]
+
+Options:
+    -h, --help         Display this message and exit.
+    -s, --secret       Display only the secret key.
+    -p, --public       Display only the public key.
+    -a, --address      Display only the address.
+    -b, --brain        Use parity brain wallet algorithm. Not recommended.
+
+Commands:
+    info               Display public key and address of the secret.
+    generate random    Generates new random Ethereum key.
+    generate prefix    Random generation, but address must start with a prefix ("vanity address").
+    sign               Sign message using a secret key.
+    verify             Verify signer of the signature by public key or address.
+    recover            Try to find brain phrase matching given address from partial phrase.

-Parity Ethereum keys generator.
-  Copyright 2015-2019 Parity Technologies (UK) Ltd.
-
-Usage:
-    ethkey info <secret-or-phrase> [options]
-    ethkey generate random [options]
-    ethkey generate prefix <prefix> [options]
-    ethkey sign <secret> <message>
-    ethkey verify public <public> <signature> <message>
-    ethkey verify address <address> <signature> <message>
-    ethkey recover <address> <known-phrase>
-    ethkey [-h | --help]
-
-Options:
-    -h, --help         Display this message and exit.
-    -s, --secret       Display only the secret key.
-    -p, --public       Display only the public key.
-    -a, --address      Display only the address.
-    -b, --brain        Use parity brain wallet algorithm. Not recommended.
-
-Commands:
-    info               Display public key and address of the secret.
-    generate random    Generates new random Ethereum key.
-    generate prefix    Random generation, but address must start with a prefix ("vanity address").
-    sign               Sign message using a secret key.
-    verify             Verify signer of the signature by public key or address.
-    recover            Try to find brain phrase matching given address from partial phrase.
